DISCUSSION
TODAY THROUGH SATURDAY...
ABOVE NORMAL TEMPERATURES AND DRY CONDITIONS ARE THE NAME OF THE
GAME THIS WEEK. HIGHS ARE FORECAST TO BE IN THE 70SF TODAY WITH
CALM CONDITIONS.
MONDAY LOOKS TO BE HOT AND BREEZY. A DRY COLD FRONT IS EXPECTED
TO MOVE THROUGH THE REGION, BRINGING WESTERLY WINDS GUSTING IN THE
20S TO 30S MPH. THE HIGHEST GUSTS ARE EXPECTED IN THE MOUNTAINS
AND FOOTHILLS WEST OF BILLINGS, AS WELL AS SOUTHEASTERN MONTANA.
HIGH TEMPERATURES ARE FORECAST TO BE WELL ABOVE NORMALS (60S AND
70SF), IN THE 80S TO ALMOST 90F. THE WARMEST TEMPERATURES ARE
FORECAST FOR THE RIVER VALLEYS SOUTHEAST OF BILLINGS, INCLUDING
SHERIDAN, WHERE THERE IS A 30 TO 60 PERCENT CHANCE OF TEMPERATURES
REACHING OR EXCEEDING 90F. CURRENTLY THREE OF THE FIVE CLIMATE
SITES COULD EXPERIENCE A RECORD HIGH TEMPERATURE. THOSE THREE
SITES ARE BILLINGS, LIVINGSTON, AND SHERIDAN.
IN ADDITION TO VERY WARM TEMPERATURES AND BREEZY CONDITIONS,
MINIMUM RELATIVE HUMIDITY VALUES WILL DROP INTO THE TEENS PERCENT
MONDAY AFTERNOON. LITTLE PRECIPITATION HAS FALLEN SINCE THE
SEPTEMBER EVENT, ESPECIALLY FOR PORTIONS OF SOUTHERN AND SOUTH-
CENTRAL MONTANA. AS A RESULT, A FIRE WEATHER WATCH HAS BEEN ISSUED
FROM 12 PM MDT UNTIL 8 PM MDT MONDAY. PLEASE TAKE CARE NOT TO
CAUSE A SPARK!
THE REST OF THE WEEK TEMPERATURES WILL REMAIN ABOVE NORMAL BUT NOT
NEARLY AS WARM AS MONDAY. ANOTHER DRY COLD FRONT LOOKS TO PASS
THROUGH MONDAY NIGHT, BRINGING HIGH TEMPERATURES DOWN INTO THE 70S
AND LOW 80SF TUESDAY. EXPECT THESE TEMPERATURES TO CONTINUE ALONG
WITH DRY CONDITIONS, RESULTING IN ELEVATED FIRE WEATHER CONCERNS
THE REST OF THE WEEK.
ENSEMBLES ARE HINTING AT A PATTERN CHANGE THIS WEEKEND, WITH AN
UPPER TROUGH IMPACTING THE REGION. THE LATEST METEOGRAMS DEPICT
SIGNIFICANTLY COOLER TEMPERATURES, PERHAPS WELL BELOW NORMAL BY
NEXT SUNDAY. CONTINUE TO MONITOR THE FORECAST IF YOU HAVE PLANS
NEXT WEEKEND!
